me to make sure! After that, my nerve went completely. I dared trust nobody.

“I think I almost hypnotized myself. After a while, I almost forgot that I was really Jane Finn. I was so bent on playing the part of Janet Vandemeyer that my nerves began to play me tricks. I became really ill⁠—for months I sank into a sort of stupor. I felt sure I should die soon, and that nothing really mattered. A sane person shut up in a lunatic asylum often ends by becoming insane, they say. I guess I was like that. Playing my part had become second nature to me. I wasn’t even unhappy in the end⁠—just apathetic. Nothing seemed to matter. And the years went on.

“And then suddenly things seemed to change. Mrs. Vandemeyer came down from London. She and the doctor asked me questions, experimented with various treatments. There was some talk of sending me to a specialist in Paris. In the end, they did not dare risk it. I overheard something that seemed to show that other people⁠—friends⁠—were looking for me. I learnt later that the nurse who had looked after me went to Paris, and consulted a specialist, representing herself to be me. He put her through some searching tests, and exposed her loss of memory to be fraudulent; but she had taken a note of his methods and reproduced them on me. I dare say I couldn’t have deceived the specialist for a minute⁠—a man who has made a lifelong study of a thing is unique⁠—but I managed once again to hold my own with them. The fact that I’d not thought of myself as Jane Finn for so long made it easier.

“One night I was whisked off to London at a moment’s notice. They took me back to the house in Soho. Once I got away from the sanatorium I felt different⁠—as though something in me that had been buried for a long time was waking up again.

“They sent me in to wait on Mr. Beresford. (Of course I didn’t know his name then.) I was suspicious⁠—I thought it was another trap. But he looked so honest, I could hardly believe it. However, I was careful in all I said, for I knew we could be overheard. There’s a small hole, high up in the wall.

“But on the Sunday afternoon a message was brought to the house. They were all very disturbed. Without their knowing, I listened. Word had come that he was to be killed. I needn’t tell the next part, because you know it. I thought I’d have time to rush up and get the papers from their hiding-place, but I was caught. So I screamed out that he was escaping, and I said I wanted to go back to Marguerite. I shouted the name three times very loud. I knew the others would think I meant Mrs. Vandemeyer, but I hoped it might make Mr. Beresford think of the picture. He’d unhooked one the first day⁠—that’s what made me hesitate to trust him.”

She paused.

“Then the papers,” said Sir James slowly, “are still at the back of the picture in that room.”

“Yes.” The girl had sunk back on the sofa exhausted with the strain of the long story.

Sir James rose to his feet. He looked at his watch.

“Come,” he said, “we must go at once.”

“Tonight?” queried Tuppence, surprised.

“Tomorrow may be too late,” said Sir James gravely. “Besides, by going tonight we have the chance of capturing that great man and super-criminal⁠—Mr. Brown!”

There was dead silence, and Sir James continued:

“You have been followed here⁠—not a doubt of it. When we leave the house we shall be followed again, but not molested, for it is Mr. Brown’s plan that we are to lead him. But the Soho house is under police supervision night and day. There are several men watching it. When we enter that house, Mr. Brown will not draw back⁠—he will risk all, on the chance of obtaining the spark to fire his mine. And he fancies the risk not great⁠—since he will enter in the guise of a friend!”

Tuppence flushed, then opened her mouth impulsively.

“But there’s something you don’t know⁠—that we haven’t told you.” Her eyes dwelt on Jane in perplexity.

“What is that?” asked the other sharply. “No hesitations, Miss Tuppence. We need to be sure of our going.”

But Tuppence, for once, seemed tongue-tied.

“It’s so difficult⁠—you see, if I’m wrong⁠—oh, it would be dreadful.” She made a grimace at the unconscious Jane. “Never forgive me,” she observed cryptically.

“You want me to help you out, eh?”

“Yes, please. You know who Mr. Brown is, don’t you?”

“Yes,” said Sir James gravely. “At last I do.”

“At last?” queried Tuppence doubtfully. “Oh, but I thought⁠—” She paused.

“You thought correctly, Miss Tuppence. I have been morally certain of his identity for some time⁠—ever since the night of Mrs. Vandemeyer’s mysterious death.”

“Ah!” breathed Tuppence.

“For there we are up against the logic of facts. There are only two solutions. Either the chloral was administered by her own hand, which theory I reject utterly, or else⁠—”

“Yes?”

“Or else it was administered in the brandy you gave her. Only three people touched that brandy⁠—you, Miss Tuppence, I myself, and one other⁠—Mr. Julius Hersheimmer!”

Jane Finn stirred and sat up, regarding the speaker with wide astonished eyes.

“At first, the thing seemed utterly impossible. Mr. Hersheimmer, as the son of a prominent millionaire, was a well-known figure in America. It seemed utterly impossible that he and Mr. Brown could be one and the same. But you cannot escape from the logic of facts. Since the thing was so⁠—it must be accepted. Remember Mrs. Vandemeyer’s sudden and inexplicable agitation. Another proof, if proof was needed.

“I took an early opportunity of giving you a hint. From some words of Mr. Hersheimmer’s at Manchester, I gathered that you had understood and acted on that hint. Then I set to work to prove the impossible possible. Mr. Beresford rang me up and told me, what I had already suspected, that the photograph of Miss Jane Finn had never really been out of Mr. Hersheimmer’s possession⁠—”

But the girl interrupted. Springing to
